TbsSQL is a small wrapper class for working with SQL databases within PHP scripts. It has few methods and two properties and it’s only one file per database for installation. Its most interesting feature is that it can protect and format values before merging them into the SQL statement. It has a cache feature, a trace mode, a debug console, and it can return data as arrays, standard objects, specific class objects, or clone objects. It can also delete PHP connection variables after making the connection.

BlackRay is a relational database system designed to offer performance features commonly associated with search engines. It offers SQL support and sophisticated operational and management features. Load-balancing and operational stability by means of N+1 redundance are included. BlackRay is called a "Data Engine" since it combines traditional, relational database features and SQL with the power and flexibility of search engines. It is a true hybrid, offering transaction support, data-versioned snapshots, and sophisticated function-based indices. Wildcards, phonetic, and fuzzy logic searches are supported, as well. BlackRay supports a subset of the SQL92 standard and provides JDBC/ODBC/native driver options via the PostgreSQL protocol, in addition to an API based query option. The project is released under the GPLv2, with some drivers available under BSD-style licenses. Commercial support contracts are available as well.

The Easysoft ODBC-Access Driver is an ODBC driver that supports both the MDB (Access 2000–2003 and Office Access 2007) and ACCDB (Office Access 2007 and later) database formats. It provides read-write access to Access databases for Linux/Unix applications. You do not need to change where your database file is located, as it supports shared locations such as a Windows or Samba share. It uses Access’ locking file mechanism and prevents users from opening a database if another user has the database opened for exclusive access, again mirroring the Access front-end’s behavior for seamless integration. It supports encrypted/encoded .mdb files, which is an Access security feature that protects Access data from unauthorized viewing.

ODBC-link is a dblink-style implementation of PostgreSQL database links. It allows users to connect from PostgreSQL to any other ODBC compliant database such as Informix, Oracle, DB2, MySQL, etc. You can integrate data from remote databases into your local query results. Writing requests is fully supported. The implementation is SQL/MED compliant.

DBD-ODBC provides the Perl DBI::DBD interface to ODBC drivers, allowing Perl access to any database that has an ODBC driver. On Unix, unixODBC is supported with Unicode. iODBC and others are also supported. DBD::ODBC supports all three methods from DBI for naming placeholders.

email@Scanner is an application that parses email from either an email server, email files, or one of several Macintosh email clients, selecting only those email that satisfy given criteria. Data may be extracted from anywhere within the selected email and further refined via data filters and scripts and then used to update a FileMaker or ODBC database. An optional outgoing email may be sent, created with data from the email and/or the associated database record.

The YB.ORM library aims to simplify writing C++ code that has to deal with SQL databases. The goal is to provide a convenient interface like SQLAlchemy (Python) or Hibernate (Java). The library itself is cross-platform and supports a variety of SQL dialects: SQLite3, MySQL, Postgres, Oracle, and Firebird. Integration with Boost, Qt4, and wxWidgets is built-in. In a typical usage scenario, you would describe your database schema and table relationships in a simple XML-based format, generate SQL code to populate database schema with tables, generate C++ classes, add application-specific logic to the classes, and use these classes in cooperation with the Session object to query objects from the database, create new or modify/delete existing objects, or link and unlink objects using relations. Simple serialization to XML is supported along with connection pooling.
